A study was conducted at Cuyahoga Community College to test the relationship between student scores on timed and untimed reading comprehension and vocabulary tests, and to investigate the relationship between those scores and intelligence. The study sample included 72 students enrolled in classes at developmental, freshman, and sophomore levels. The students were given the Nelson Denny Reading Test (NDRT) both as a timed and an untimed test, and their NDRT results were compared with their scores on the Degrees of Reading Power (DRP) test and on the Peabody Picture Vocabulary Test (PPVT). Study findings, based on the scores of the 57 students who took all three tests, included the following: (1) the DRP and NDRT measured different types of reading communication; (2) the DRP tended to overestimate students' reading abilities, and underestimate the number of high-risk students; (3) the vocabulary section of the NDRT showed potential for use to estimate students' academic potential; and (4) reading comprehension and intelligence were correlated.
